Application filed November 28, 11923 Serial no. $77,493.

To (slime/torn its may concern Be it; \known that I, Enmoo Rn, a subjectof-the .King of Italy,-residing"at Vinelanchi in,thecounty ofGun'iberlandand Stateof Newwlersey, have invented certain new and usefulImprovements in .h lotors, 1 of which thewfollowing is -a speeification,reference being had to the accompanying drawings, This invention relatesto certain improvementstin.motors and it is primarily an object of theinvention to provide a novel and improved device of this generalcharacter especially designed and adapted for use in operating thetreadles of the operating mechanism of a player piano. 7

It is also an object of the invention to provide a novel and improvedmotor of this general character which isof a spring type and wherein theoperating shaft has asso ciated therewith a plurality of spring operated members whereby the device can be constructed in a manner to occupya minimum of space yet at the same time possess the efficiency desiredin a device of this kind. V e

The invention consists in the details of construction and in thecombination and arrangementof the several parts of my improved motorwhereby certain important advantages are attained and the devicerendered simpler, less expensive and otherwise more convenient andadvantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitelyclaimed.

In order that my invention may be the better understood, I will nowproceed to describe the same with reference to the accompanyingdrawings, wherein Figure 1 is a view partly in section and partly inelevation illustrating a motor constructed in accordance with anembodiment of my invention;

Figure 2 is a sectional view taken substantially on the line 22 ofFigure1; V

Figure 3 is a fragmentary sectional view taken longitudinally of Figure2.

As disclosed in the accompanying drawings, H denotes a housing ofsuitable dimensions and which is supported at its opposite ends by thepillars or posts P whereby the device may be readily disposed V over thetreadles T for the operating mechanism of a player piano; The posts orpillars P have associated therewith the casters C whereby the device inits entirety may function.

Rotatably supported within [the housing 1 H is a crank shaft 1 which hasioperativelyi engaged therewith the 1 pitmen :2 which 1 are 1 adapted tobe iconnected :in anycpreferred manner with the treadlesT 'soithat uponrotation of the shaft 1 the treadles .;T,will be. operated}. inzaamanner to; effect the dz.- sired functioning of the operating mecha-.nism of the player piano and without the necessity. of the treadlesbeing worked by the'feet as is now done.

Also supported within'the housing H is a second shaft comprising aplurality of sections 3and mounted on each of said sections is a gearwheel 4 in mesh with the pinion 5 mounted on the shaft 1 so that uponrotation of any one of the gears 4 the shaft 1 will be rotated.

Each of the gears 1 is loosely mounted on the shaft 1 but provided witha pawl or dog 6 associated with the ratchet wheel 7 fixed to theshaft 1. gears 1 offer no obstruction to the rotation of the shaft 1 butupon any one of the gears becoming inactive, the desired rotation of theshaft 1 will be affected.

The gears 4 are also each loosely mounted on a shaft section 3 and isprovided with a dog or pawl 8 coacting with the ratchet wheel 9 carriedby the shaft section 3. Associated with the gear 4: and the shaftsection 8 is a spring 10. 1

Each of the gears 4 is normally maintained inactive by the pivot dog 11normally held in looking engagement with the spring by the springpressed pin 12. A rock lever 1d has one end portion overlying the dog 11and its opposite end portion dis posed over the periphery of an adjacentspring 10 so that as said spring 10 unwinds and is substantiallycompletely run down, said spring will contact with the lever 1 1- androck the" same. in a direction to release the dog 11 whereupon the nextsucceeding spring and gear 1 will be caused to The first lever 14:,however, eX- tends eXteriorly of the housing H and is adapted to beengaged by a finger or the like to initially start the motor.

Any means, as generally indicated at 15, may be employed for winding thesprings it is also to be understood that the en- By this means the idle7 gagement of the pitmen 2 with the treadles T is detachable.

From the foregoing description it is thought to be obvious that a motorconstructed in accordance with my invention of shaft sections rotatablysupported adjacent to the shaft, a gear loosely mounted on each of theshaft sections, a gear loosely mounted on the first named shaft withwhich said gear of the shaft section meshes, a spring associated Witheach shaft section and gear thereon for rotating the gear, coactingmeans carried by the shaft and each of the gears mounted thereon tocause said gear and shaft to rotate in unison in one direction, meansfor holding the gears on the shaft sections against rotation, the springassociated with one gear operating when unwound to release the holdingmeans of the succeeding gear.

In testimony whereof I hereunto aliix my signature.
